What is jSDM?
Joint species distribution models in Gibbs-sampled C++, quiet since 2023.
jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.
What is Tailscale?
Tailscale is paying down scale in two dimensions: nodes per tailnet, tailnets per org.
Three threads run through this window. The tailnet management API is the newest: creation landed in alpha in late July, and the list endpoint now paginates at 100 results with limit and cursor parameters. The client releases are patch-grade but weighted toward scale — v1.102.1 made node additions and removals constant-time, and v1.102.3 fixes Tailnet Lock startup failures on large tailnets while cutting memory use on iOS and tvOS. The Kubernetes operator runs on its own track, adding in-cluster PeerRelays, workload identity federation and IPv6 egress.

jSDM
0.0INFRA · APIS
Joint species distribution models in Gibbs-sampled C++, quiet since 2023.
◆ Current state
jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.
◆ Where it's heading
The package built out its model family quickly and then stopped: five of the six visible entries are stamped the same day as a backfilled archive, and the only later release says nothing about its contents. The direction the 0.2 line was heading, toward trait-mediated species effects and better convergence on latent variable models, has no visible continuation.
◆ Prediction
The feed does not support a confident prediction; the latest entry publishes no notes, so whether the package is still developing or only being kept CRAN-clean cannot be read from it.
Tailscale
6.3INFRA · APIS
Tailscale is paying down scale in two dimensions: nodes per tailnet, tailnets per org.
◆ Current state
Three threads run through this window. The tailnet management API is the newest: creation landed in alpha in late July, and the list endpoint now paginates at 100 results with limit and cursor parameters. The client releases are patch-grade but weighted toward scale — v1.102.1 made node additions and removals constant-time, and v1.102.3 fixes Tailnet Lock startup failures on large tailnets while cutting memory use on iOS and tvOS. The Kubernetes operator runs on its own track, adding in-cluster PeerRelays, workload identity federation and IPv6 egress.
◆ Where it's heading
The qualifier that keeps recurring is “large”: tailnets big enough to break Tailnet Lock at startup, node churn that pinned CPU, mobile clients running short of memory, and organizations holding more than a hundred tailnets. Tailscale is absorbing the cost of customers who outgrew the shape the product originally assumed, in two directions at once — nodes inside a tailnet, and tailnets inside an organization. The second is the more consequential, because allocating a tailnet per customer or per environment is a different product than a company network. Security work stays continuous alongside it, with TS-2026-011 closed here and a run of SSH and Serve advisories backported the month before.
◆ Prediction
The tailnet creation API should leave alpha carrying the same limit-and-cursor contract just applied to the list endpoint, with further startup and memory work aimed at large tailnets on the client side.
